Description of Fulcrum Speed 55T Carbon Wheelset Tubular

Fulcrums engineers spent hours and hours in wind tunnels. They studied the effects of rolling on the structure of the rim to make a wheel dedicated to the very essence of speed, when average speeds are really high and every watt has to count. The new 55 mm design is the latest response to the historic challenge of headwinds and attrition.

3K carbon rims are used in the Speed 55T wheelset which are suitable for tubular tires. Using the solid and ultra-responsive structure - made possible thanks to the rear oversize flange and the Two-to-one™ spoke pattern - as a basis, Fulcrum has created an rim, fibre after fibre, to enhance performance in two crucial moments of a race: acceleration and braking, which has now been optimized for any weather condition thanks to the use of AC3™ technology.

55 mm is the size to choose if you are aiming to increase your power output and make the most of the flywheel effect created by the rotation of the rim: incredible speeds plus optimum support during the strongest accelerations. This versatile wheel is ideal for short climbs out of the saddle, when cycling on the flat or in triathlon races when making the most of aerodynamics is key.

Features of the Fulcrum Speed 55T Carbon wheelset:

Rims: 55 mm deep 3K-carbon rims with 24.2mm width. Their brake tracks are featuring AC3 - All Conditions Carbon technology. It uses micro laser incisions on the surface to eliminate resins and to achieve better roughness.

Rear hub with oversize flange: Carbon hub with oversize aluminum flange and Two-to-One™ technology: the doubling of the spokes on the cassette side provides greater torsional stiffness and therefore a greater reactivity at each pedal stroke. This means greater efficiency in the transmission of power to the wheel. Smoothness is ensured by ceramic bearings.

Front hub: The front hub features a carbon body, aluminium flanges and small dimensions so it is extra light. Also equipped with ceramic bearings.

2:1 Two-to-One™: On the rear wheel the number of spokes on the drive side is twice as much that of the opposite side. Greater stability of the wheel thanks to the perfect balance between the spoke tensions - greater torsional stiffness and greater reactivity.

Aerospokes: This setup provides stainless steel aero spokes. They ensure optimal rigidity and aerodynamics.

Nipples: The nipples are specially shaped to facilitate the assembly process and to stay in place without the addition of any other cushioning material.

MoMag™: Allows the external profile of the rim to be free of holes - increases structural resistance - makes a rim tape unnecessary and reduces the weight of the wheel.

P.E.O. (Plasma Electrolytic Oxidation) coated freehub body: The freehub body for Shimano-SRAM will be submitted to Plasma Electrolytic Oxidation treatment in the laboratory. Despite the thickness of the material being reduced to the minimum, the duration and strength are maintained with the benefit of a lower weight.

Anti-rotation System™: Keeps the spokes in the position of maximum aerodynamic penetration.

Cult™ - Ceramic Ultimate Level Technology™: Behind this project is the exclusiveness of Cronitect® steel, using “Advanced by FAG” technology by Schaeffler Group employed for the bearing races. This steel is resistent to the corrosion of the highest level until the point that no grease is necessary for lubrication, maybe just a small amount of oil. The top quality ceramic balls, thanks to the absence of lubricating grease and the precision machine of the cup and cone technology, allow to reduce the friction coefficient drastically and then increase the smoothness of triathlon and road bike wheels by as much as 9 times compared to standard bearings..
